Unleash the full potential of your Mustang's 4V engine with the best long tube headers on the market. Kooks long tubes are made from aircraft quality T304 stainless steel. Kooks only uses the highest quality stainless steel unlike their competitors. 1-3/4" tuned primaries merge into 3" collectors to create the the smoothest flowing path. Every collector features Kooks' scavenging spike to ensure maximum flow. Laser cut 3/8" thick flanges ensure no warping or bending occurs. Each port is hand ground to make sure they are perfectly smooth so there is no exhaust constriction. Kooks systems are bolt-in and never require any cutting or welding. O2 extensions and all necessary hardware are included.

Each Kooks exhaust system is designed specifically for the engine and vehicle it is built for. Kooks utilizes the firing order of the engine when designing their exhaust tubes. The most technically advanced equipment is used when designing Kooks exhaust systems. Every system is dyno and race tested to ensure the results are up to Kooks' expectations. This means Kooks can guarantee their exhaust makes the most horsepower and torque in the industry. All Kooks products are manufactured in a 45,000 square foot state of the art facility located in Statesville, North Carolina.

Kook's Headers has been in business since 1962. With over 50 years of header and exhaust knowledge, you're guaranteed the best quality products. Kooks is involved with all types of automobile racing and makes parts for the ARCA, Lucas Oil Series, IMCA, URA and many other oval style racing series. Kooks is also an official contingency partner with NASCAR. Drag racing was the back bone of Kooks but they also supply cars in the SCCA and NASA. Kooks is a top supporter of the NHRA, ADRL, NMCA, NMRA, Fun Ford Weekend, PTRA and many more.

Just bought a 1998 SVT Cobra to road race with the usual - 4.6L, 4V, 5 spd. I prefer Kooks long headers, but the folks at the dyno shop I use advised me the Kooks shorties mount with less problems and dyno out just about the same. Comments? Thanks!

We do not offer a system for the 4.6L 4V that has shorties. We only have long tubes and they dyno out very strong.
